GQ8A034120FAT

GQ8A034120FAT Description

The GQ8A034120FAT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. Encased in a ceramic QSOP package, it offers 412Ω resistance per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. The 16-pin gull-wing SMD configuration enables reliable surface-mount assembly, while its 0.75W total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for demanding circuits. The isolated (ISOL) circuit design provides flexibility in routing, and the ceramic substrate enhances thermal performance. Packaged in a tube, it is ideal for prototyping and small-batch production.

GQ8A034120FAT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Ceramic QSOP Package: Combines durability with compact dimensions (4.9mm × 6.02mm × 1.47mm).
• Isolated Resistor Network: Enables independent routing without shared terminals.
• Wide Temperature Range: Operates reliably from -70°C to +125°C with derated power at higher temps.
• Low TCR (±25ppm/°C): Minimizes resistance drift in fluctuating environments.
• Gull-Wing Termination: Ensures robust solder joints for high-reliability SMT applications.

GQ8A034120FAT Applications

This resistor network excels in:

• Industrial Control Systems: Signal conditioning, feedback loops, and voltage dividers.
• Medical Electronics: Precision instrumentation requiring stable resistance values.
• Telecom Infrastructure: Line termination and impedance matching in high-frequency PCBs.
• Automotive (Non-Automotive Rated): Sensor interfaces or infotainment systems where isolation is critical.
• Test & Measurement Equipment: Calibration circuits and reference networks.

Conclusion of GQ8A034120FAT

The GQ8A034120FAT stands out for its precision, isolation, and ceramic-enhanced reliability, making it a superior choice over plastic-encased networks. Its thin-film construction and tight tolerances cater to high-accuracy designs, while the QSOP footprint saves board space. Though not RoHS-compliant, it remains a robust solution for industrial, medical, and telecom applications demanding thermal stability and electrical isolation. Engineers will appreciate its balance of performance and packaging efficiency in critical circuits.
